Abstract

Depth estimation from monocular images can be retrieved from the perspective distortion. One major effect of this distortion is that a set of parallel lines in the real world converges into a single point in the image plane. The estimation of the co-ordinates of the vanishing point can be retrieved directly on the Hough Transformation space or polar plane. In fact the vanishing point in the image plane is mapped in the polar plane into a sine curve that can be estimated with a simple linear system.
